Anwser is #1 because t<span>he equator is moving faster than the poles and so extends outward a bit due to centrifugal force. That means a point on the equator is a tiny bit farther from the centre of the Earth than the poles. </span>
<span>The gravitational acceleration at the equator is 9.789 m/s^2m, and 9.832 m/s^2 at the pole.</span>

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Anton [14]

Answer: blood calcium level

Explanation:

There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity

, systemic blood pressure, and renal artery/arteriole diameters.

Filtration membrane integrity

: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.

Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.

Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.

Blood calcium level do not have any role in the kidney filterate formation or renal regulation.

Hence, the correct option is blood calcium level.

Explain what terms in the Hardy-Weinberg equation give: allele frequencies (dominant allele, recessive allele, etc.) each genoty
zysi [14]

Answer:

Explanation:

Hardy Weinberg equation is presented below and describes that in a population the frequency of alleles ad genotypes will remain static or the same in the absence of evolutionary disturbances such as mutation, migration ( gene flow), natural selection and with the population large and random mating

p² +2pq + q²

where p represents the frequency of the dominant alleles

q represent the frequency of the recessive alleles

p² represent the frequency of the dominant homozygous genotype

q² represent the frequency of the recessive homozygous genotype

2pq represent the frequency of the heterozygous genotype

q² also represent the frequency of the recessive phenotype

(p² + 2pq) represent the frequency of the dominant phenotype

Which substance is a compound? <br> salt <br> phosphorus <br> sulfur <br> oxygen
tankabanditka [31]

Answer: The correct answer is salt.

A compound is a chemical substance which is formed by the combination of two or more elements, joined together in a fixed proportion.

Salt is a chemical compound which is formed by the reaction of an acid with a base. For example- NaCl ( sodium chloride) is a common salt. It is formed by the combination of two elements. Therefore, salt is a compound.

On the contrary, Phosphorous (P), sulfur (S) and Oxygen (O₂) are composed of a single element. Therefore, they are not compounds.

Thus, the correct answer for the compound is Salt .
